 Description   

After 6.0, we should start generating the new, standardised token format for all events. This will require us to set the default token version to 2, to make $_generateV2ResumeTokens an optional parameter, and to have mongoS and mongoD assume that its value is true unless it is present and explicitly false. This ticket should also include upgrade/downgrade work to ensure that a change stream can survive upgrades between 6.0 and later releases.

Per a conversation with bernard.gorman, the question is whether we can do this immediately after 6.0.0-rc0 or if we have to wait until the FCV constants are updated. Will check in again after rc0.
